  • -b kbufsz : try and reserve a kernel buffer of kbufsz bytes for the netlink queue. Too large a buffer wastes kernel memory; -too small a buffer risks losing events. The default is 196608 -(192 kB, which is on the large side for average systems).
    • +too small a buffer risks losing events. The default is 500 kB, which should be +enough for most systems; if you're getting "No buffer space available" errors +from mdevd at coldplug time, try increasing this number.
  • -n : dry run. mdevd will not create or delete device nodes, and it will not spawn commands. Instead, it will print to stdout the actions it would have performed.
